Canadian authorities found a woman's torso floating at the bottom of Niagara Falls last Wednesday, and they suspect it may be a missing American, the AP reports. Police have classified the case as a homicide investigation, and “we are prepared to say that it was a dismemberment," says a Canadian police spokesman. Investigators have pored over 50 or so Canadian missing-person case files, but believe none "fits the parameters" of the discovered body, Niagara's regional police inspector tells the Niagara Falls Review.

“We have met with our American policing partners who continue to review missing-persons reports in their jurisdiction," he says. State police have a begun a search through missing person records in New York, but may expand the investigation to other states. “There’s a good possibility this person entered the water from the US,” says a state police spokesman. The body, missing limbs and a head, is that of a middle-aged white female with a pierced navel.
